In October 1993, HMT-301 was deactivated and HMT-204 became the single site Fleet Readiness Squadron for the entire Marine Corps CH-46E community.

HMT-204 FREST provides comprehensive technical training for officers and enlisted in the operation, maintenance and repair of the CH-46E aircraft and associated equipment.

In recognition of this significant achievement, the squadron has been the recipient of the Chief of Naval Operations Safety Award in fiscal years 1977, 1994, and 1997.

VMMT-204 received in April 1999, from Raytheon Systems Company, a new motion-based operational flight trainer (OFT) to train Marine Corps and Air Force instructors to fly the Osprey.

Both out-of-window visual scenes and forward-looking infrared imagery are made possible by the OFT's six-channel visual-display system.

Its full range of motion also allows pilots to get "a real feel" of both acceleration and deceleration and gives them the opportunity to train in a broad spectrum of simulated environments.
